ATTORN EYS U.S. Cl. 83-412 4 Claims ABSTRACT F THE DISCLOSURE A die cutting machine for cutting labels for phonograph records and the like wherein the label has a center hole and the label is to be circular about the hole aS a center. A pin is provided on which the uncut labels are placed with the pin passing through a precut hole through the center of the stack of labels and means are provided in connection with initiation of the cutting stroke to insure centering of said pin with respect to the die.

Cross reference to related application This application is somewhat related to a copending application in the names of Brestel and Maschinot, Ser. No. 630,989, tiled Apr. 14, 1967, and entitled Label Die Cutting Machine. In that application there is disclosed and claimed an arrangement for increasing the stroke and speed of stroke of the pusher. The arrangement there disclosed may of course be applied to the present machine if desired.

Background of the invention The invention pertains to label die cutting machines wherein a stack of uncut labels is moved from a loading position to a cutting position on an anvil and the anvil is then pushed upwardly against a cutting die. In particular it relates to a machine for cutting phonograph record labels and the like wherein the stack of labels is provided with a drilled center hole and where it is desired that the circular label be concentric with the center hole.

The basic machine to which the invention relates is similar to that shown in the Brestel and Maschinot Patent No. 3,290,977. A machine of this type usually consists of a table with an anvil normally level with the table onto which a stack of labels is pushed by a feeding means and the anvil is actuated by means of a cam and a ram to lift the anvil and push it against the cutting die. The main motor of the machine drives the cam and also produces reciprocation of the pusher element which moves the labels from loading position to cutting position.

Where ordinarily square or rectangular labels are to be cut, the pusher means simply push against an edge of the stack of labels to move them into cutting position. In connection with phonograph record labels it is very desirable to have the label concentric with the center hole of the record so that they do not appear to wobble as the record turns on the turntable.

Summary According to the present invention, the stack of labels will have a center hole predrilled. The table and anvil are provided with aligned ways and a slide block is slidably mounted in said ways so as to be able to move through the ways in the table and into the ways in the anvil. As the anvil rises, the slide block rises with it and a connection is provided between the slide block and the pusher to permit relative vertical movement between the two without disconnection from each other. A pin is mounted on the slide block and the stack of labels to be die cut is placed over this pin so that the stack of labels is moved 3,455,195 Patented `luly 15, 1969 ice by contact between the pin and the center hole through the stack from the loading position on the table to the cutting position on the anvil.

There is provided a centering extension beneath the silde block which is arranged to cooperate with a centering socket on the ram which moves the anvil in its cutting stroke. A lost motion connection is provided between the ram and the anvil so that the anvil does not partake of the movement of the ram until centering is complete.

Brief description of the drawings FIG. 1 is a more or less diagrammatic front view of the machine with parts in section and with the slide block and pin in loading position.

FIG. 2 is an enlarged view of the pusher and slide block portion of the apparatus on an enlarged scale.

FIG. 3 is a view similar to FIG. 1 showing the pusher at the end of its loading stroke.

FIG. 4 is a view similar to FIGS. 1 and 2 showing the parts as the ram is at the top of its cutting stroke.

FIG. 5 is an enlarged perspective View showing the anvil, slide block, pusher and the connection therebetween; and

FIG. 6 is a fragmentary view showing the lost motion connection between the ram and anvil.

Description of the preferred embodiment As will be clear to those skilled in the die cutting machine art, there is provided a base 1 and an upstanding column 2. A table 5 is provided over which the labels are moved from a loading position to a cutting position. The table is, of course, provided with a slot for the passage of the pin 6 which will be described in more detail hereinafter. The pusher is indicated at 7 and is actuated by means of the lever 8 as actuated by the cam 9. The lever 8 is pivoted at 10 and has a short arm 11 carrying a cam follower 12 cooperating with the cam 9. The rod 13 and spring 14 connected as shown are for the purpose of maintaining the follower 12 in contact with the cam 9.

From the foregoing, it will be clear that as the main shaft of the machine 15 is rotated by the main motor (not shown) the cam `9 rotates and causes the lever 8 to swing back and forth between the pulls of FIGS. 1 and 3, thus reciprocating the pusher 7.

The pin 6 is mounted in a slide block 16 which rides in aligned ways in the table 5 and the anvil 17. Fixed to and depending from the slide block 16 is a rod 18 which passes through a hole 19 in the pusher 7. The rod 18 is of such length that as the anvil 17 is moved upwardly carrying with it the slide block 16, the rod 18 does not become disengaged from the pusher 7. Thus, a substantially rigid connection for movement in a horizontal direction is provided for the pusher 7 and slide block 16,

whereas relative movement in a vertical direction is permitted.

From the foregoing, it will be clear that a stack of labels having a central hole is placed over the pin 6 with the machine in the condition of FIG. 1 and rotation of the shaft 15 then moves the pusher 7 and slide block 16 to the position of FIG. 3 which is the cutting position.

It is very important that the pin 6 be centered with respect to the cutting die which is mounted above the anvil and not shown in these drawings because it does not constitute a -part of the invention. There is provided between the ram 20 and the anvil 17 a lost motion connection so that during initial movement of the ram the anvil does not move and a centering of the pin 6 may be accomplished. This mechanism can best lbe understood from a consideration of FIG. 6. The ram 20 reciprocates in a housing 21. It is reciprocated by means of the cam 22, also xed on the shaft 15. Secured to the upper end of the ram is a plate 23 and a pedestal 24. The pedestal 24 is provided at its upper end with a conical centering socket 25. A plurality of pins 26 having the heads 27 are iixed to the anvil 17 passing through bushings 28 in the plate 23. Compression springs 29 are disposed about the pins 26 between the plate 24 and the anvil 17. The housing is provided with the stop buttons 30'.

It will now be clear that as the cam` 22` causes the ram 20 to begin its upward movement, the plate 2,3` and pedestal 24 and centering socket 2S are carried upwardly but the anvil remains stationary. It is not until the plate 23 abuts the anvil 17 that the anvil too is carried upward. The centering socket 25 cooperates with a tapered centering extension 31 aligned with the pin 6. Thus, if the pin 6 and centering extension 31 are not properly centered with respect to the axis of the ram and the axis of the die, contact between the conical extension 31 and the conical socket 25 during initial :movement of the ram provides for accurate centering. Thereafter, when the plate 23 abuts the anvil 17, the cutting stroke takes place,

It will be understood that various modifications may be made without departing from the spirit of the invention. No limitation not specically set forth in the claims should therefore be implied.
